Yeah I know about that map. It's from 4 dungeon magazines and Paizo was publishing them at the time. I haven't bought one of them so I don't know if they are original or something they printed to sell back when the magazine published and they are still selling them off. Either way, I am sure they have the licensing rights to sell it. As for new products, WOTC owns the rights to Greyhawk and right now you just cannot publish commercially for it.

They are not by Darlene, but by Robert Lazzaretti who also did the 1e Golarion map.

I would be ready to pay for such a map. It is a shame that WotC does not open up on Greyhawk.

Thank you. I look foward to it, but take as much time as you need. So far, the results are gorgeous.
My Greyhawk map v1.1 is up and finished for the time being. I added the missing locations, fixed some spelling errors, and fixed a few label issues. The new Easyzoon version will allow you to take snapshots at any zoom level or download the full resolution file. Enjoy, I hope somebody finds it useful.
